Delegates at the Democratic National Convention in the state of North Carolina will vote on Tuesday to adopt their party platform - a sweeping, non-binding document that spells out the party's positions on domestic and international issues.

Republicans put forward their own platform during their national convention in the state of Florida last week.

-Seek to modernize Medicare and say the program, in its current form, is unsustainable.

IMMIGRATION

Democrats:

-Want comprehensive immigration reform that would bring undocumented immigrants "out of the shadows," requiring them to "get right with the law, learn English and pay taxes" to be considered for citizenship.

Republicans:

-Oppose any form of "amnesty" for those who "by intentionally violating the law" when entering the United States "disadvantage those who have obeyed it."

ECONOMY

Democrats:

-Seek to extend tax cuts put in place under Republican President George W. Bush for Americans earning less than $250,000 a year.

-Support the expiration of tax cuts imposed at the same time for those earning more than $250,000.

Republicans:

-Seek to extend the Bush-era tax cuts for all Americans, pending reform of the federal tax code.

-Want to rein in government spending and reduce regulations.

SMALL BUSINESSES

Democrats:

-Call U.S. small businesses the "engine of job growth in America."

-Support tax cuts for small businesses enacted by President Barack Obama.

Republicans:

-Call small businesses the "backbone of the U.S. economy."

-Seek to reform the tax code to allow businesses to "generate enough capital to grow and create jobs."

ENERGY

Democrats:

-Seek to reduce U.S. reliance on foreign oil by developing domestic wind, solar, geothermal, nuclear and hydropower, biofuels, oil, clean coal and natural gas, as well as by increasing energy efficiency in buildings, industries and homes, and promoting "advanced" vehicles and fuel economy standards.

-Want to protect "sensitive" public lands, including the Arctic National Wildlife Refuge, from exploration.

Republicans:

-Support opening the coastal plain of Alaska's Arctic National Wildlife Refuge for exploration.

-Seek allowances for more oil and natural gas exploration on federally owned and controlled land.

MIDDLE EAST HOT SPOTS

Democrats:

-Iran: Support President Obama's commitment to "using all instruments of national power" to keep Iran from acquiring nuclear weapons.

-Syria: Vow to work to end regime of President Bashar al-Assad and support a political transition.

Republicans:

-Iran: Say the threat of a nuclear Iran has grown under President Obama because of a "failed engagement policy."

-Syria: Support a transition to a "post-Assad Syrian government" that would be "representative of its people."
